Abstract

The paper is devoted to objectification and determination of the influence of hand-arm vibrations with selected machinery. We permanently meet with vibrations, but especially when performing work activities. When working with machinery, a person is constantly exposed to vibrations and they can very negatively affect the health of the person. The aim of the paper is to compare measured vibration values with the manual of the device and then to determine the maximum time exposure for work activities to avoid the employee being at risk of working with the device. Comparison of a final hand-arm vibration will be assessed by means of the hand-arm exposure calculator and software for a specific measuring device – vibration analyzer of the 4447 type. The proposed method – an extended risk matrix – is used to assess the risks of hand-arm vibration.
